The present invention relates to a coronal core type microgel emulsifier obtained by polymerizing a polyethylene oxide macromonomer, a hydrophobic monomer and a crosslinkable monomer under specific conditions. And a water-oil emulsion composition obtained by emulsifying the crown-shaped nucleus microgel emulsifier and the emulsifier. The object of the present invention is to provide an emulsion having excellent emulsion stability, stability over time, low skin irritation, no stickiness when applied, moisturized without powdery feeling or rough feeling, and the sustained effect of the flavor is also A novel crown-shaped nucleus microgel emulsifier having an excellent oil-in-water emulsified composition; and an oil-in-water emulsified composition obtained by emulsification using the emulsifier. |
